Be it. known that I .lonx-YH. Piinnnn, acitizen of the l niteil States, residing at Jersey City in the county of Hudson and State of New Jersey. lHU' invented certain ne-\ and useful Iinprowuwn'ts in Selflh'eeding Pens; and I do herrl r declare the following to he a. full elem mul exact description of the invention, sueh as will enable others skilled in the art to rhieh it zipper-thinsto make and usethe sum-e.

This invention. relates to feeding pens and one ofthe principal objects of the in ention is to provide it pen having ir cap or reservoirprovided "with n compressible bulb or (container for the ink, and a tube leading from the container to near the point or points of thepen, and means being pro YidHi for compressing the bulb, or for relieving the pressure therefrom to either feed the ink to the points of the pen or for filling the bulb.

Another object of the invention is to pro ride a compressibleiiik reservoir having a tube leading to near the-pointor points of the pen and a plug or button connected to the. end of the barrel of the pen and slirizihle therein to operate the con'qn'essing derice for hearing against the reservoir for expelling inl: through the tube.

i he foregoing and other objects nn be nttninerl by means of the construction illus' trziteil in the ncr'r-ompnnying (lrnn'infg'js in iv h irl i-- Figure l is :1 side elevation ol :1 drafting pen naznle in :zerorihuiee with this inrentimn Fig. '3 is longitiulinfii siu-iionnl View ol the some, big. i is 2: transverse serlionnl iew taken on line i of Fig 2, looking'in the direction iiuliontwl by the arro s, moi Fig. l is a si ie elerntion of the sour w; sor 'tor expelling the inli ll'fllfl the ink rrvoir.

The ink reservoir is hollow r nd .(5on1rooted--- to the lower end thereof is :1 tuh'e'a whi'eh extends through the bore'i'n the reduce-(1 portion 2 through the bore the partition 5, and through the opening 10 in the solid portion 7 (rt-the pen point-s, said tube ter-' inixmting at near the points c'ofthe pen. The feed tphe ljl llliiy have 11- eontraoted opening at meend I). I

3x flat strip of spring metal is 'loczite ci irithin zllKlQXtClidS iongitudinaliy of the barrel 1. This strip hos its ends offset to provide a compression member 1 1- and nt tziehing members 14 and 14:. The'attnclr in g member H is secured to the barrel. 1 by a pin 13, and the attaching member H" is secured to a: plug or button 15 slidably mounted in the outer end of the barrel 1. The compression nn-mber 14. is straight and is zipproxinnitelv as longns the reservoir AI, run: it is nl-\'2i YS in light. contact with one sirle oi the reservoir. I

The operation oi" the self-feeding pen may liebriefly described as follo\\-'s2.\' r'hon it i-= desired to fill ihe pen. the plug 1:) pushed iunz-u-dly. This movement of tho causes the entire length of the compression member It to be hurried in the'riireriion of the for Wall of the res-rr-oir A, resulting in the romplete (inflation of the reservoir: With the reservoir in this condition, the ion or end of the tuhr 1 is insert-oil in n borly of ink, utter which the liillfli is released. 4\s soon as thrplng relezisml, the elasticity of the strip forres the ping outwardly zuul r turns the voznpression iinr H to its original position. permitting (h5- reservoir to assunuits original vomlilion nmi the iuihition oi the eservoir "will (ilzHY ink throo i'i the prning in the points of the tube (1 ions plug 'fillingthe reservoir'Ai When it is desired to feed the ink through the contr: wted open? ing in the tube a, the-plug 15 may be slightly pushed into the barrel 1 to bow the com- 5 pressor 1 against the reservoir.

Various changes may be made in the-details of construction without departing from the spirit-,andfscope of the-invention as defined in the elaim 5 What is claimed-is A self-filling fountain pen comprising a barrel, a nib at one enjdof the barrel, a plug slidably mounted in the other end, of the barrel, a compressible reservoir located within the barrel, a tube'leading'from the reservoir to the nib, a stripof flat spring metal located within and extendinglongitudinally of the barrel, said "strip having its ends offset to.provide attaching members and an said compression member having a length intermediate straight compression member,

approximately equal to the'lengthof the reservoir, and normally lying' in, Contact. with one wall of the reservoir, one "of said' attaching .members being secured, to said '3 plug, and means securing the other attaching member to said barrel, the entire length of the compression member being moved'in the direction of the oppositewall of the. reservoir when the plug is forced into the 3 barrel resulting in the complete deflation of 1 the reservoir-and the' elasticity of said strip returning the compression member its original position when the plugis released,

permitting the reservoir, to return to its 0 original condition to permit the reservoir to be filled with ink.. a 1 in testin'iony whereof I affix my signature I in presence of two witnesses. v 7
